Some Questions

Hi:

   I have a question on calling a method in PHP.

suppose I have file class1.php which contains class1
<?
  class class1{
      var $a1;

      function class1()
      {
        $this->a1 = "hello";
      }

      function t1()
      {
          return $this->a1;
      }
  }
?>
in test.php I have the ff:
<?
    include("class1.php");
    $obj = new class1();
    $a = "test";

    die("this is $a message=$obj->t1()");
?>

    The message displayed is always:
        this is test message=()
    instead of :
        this is test message=hello

  is there another way of doing it aside from:
  $x = $obj->t1();
  die("this is $a message=$x");


Thanks in advance,
ludwig lim
